[PATCH] D34711: [opt-viewer] opt-viewer.py takes -o argument

[Brian Gesiak via Phabricator via llvm-commits]

modocache created this revision.
Herald added a subscriber: fhahn.

Change how the output directory is specified when invoking
opt-viewer.py, from `opt-viewer.py yaml_file_one yaml_file_two output_dir` to
`opt-viewer.py -o output_dir yaml_file_one yaml_file_two`.

This makes it easier to pipe the results of another command into
opt-viewer.py. For example:

  find . -name "*.yaml" -print | xargs /path/to/opt-viewer.py -o html
